That means CO2 emissions will be more than 2.5 tonnes less per net, per year.The lightweight nets are made from an ultra-high molecular weight polyethylene – described as the strongest fibre in the world – and weigh around nine kilos, half as much as traditional cargo nets.

There are more advantages to the nets than emissions savings.Operatives will be able to handle them more easily and safely, and because the nets are more damage-resistant than polyester versions, they require around half as much maintenance, says a statement.
